For ivars created using @synthesize, set their DeclContext to be
the @implementation (instead of the @interface) and actually add
the ivar to the DeclContext (which we weren't doing before).

This allows us to simplify ASTContext::CollectNonClassIvars() by
removing ASTContext::CollectProtocolSynthesizedIvars().  Now all
ivars can be found by either inspecting the ObjCInterfaceDecl and
its companion ObjCImplementationDecl.

Add preprocessor guards to the definitions of size_t and wchar_t, and #undef NULL before defining it.
This addresses potential issues with system headers reported in <rdar://problem/7727159>.

already know about.
